    <p>Hará cosa de un año que me mudé de servidor. Bueno, en realidad llamé a un amiguete para que me echara un cable porque yo no fui capaz. El hecho es que desde entonces me pasan cosas raras. Una de ellas es que, cuando subo una imagen me da el siguiente error:</p>
    <p>

    Code:
    Warning: realpath() [function.realpath]: Unable to access /usr/home/adesgana.com/web/blog/wp-admin/wp-content/uploads in /usr/home/adesgana.com/web/blog/wp-includes/functions.php on line 1767</p>
    <p>Warning: realpath() [function.realpath]: Unable to access /usr/home/adesgana.com/web/blog/wp-admin/wp-content/uploads in /usr/home/adesgana.com/web/blog/wp-includes/functions.php on line 1767</p>
    <p>Warning: realpath() [function.realpath]: Unable to access /usr/home/adesgana.com/web/blog/wp-admin/wp-content/uploads in /usr/home/adesgana.com/web/blog/wp-includes/functions.php on line 1767<br />
    1486

    </p>
    <p>Pero la imagen sube. De hecho esto así es como me aparece en la biblioteca de objetos:<br />
    imagen1qdt.th.png</p>
    <p>Además de todo lo dicho, me crea una especia de subpost que contiene la imagen y en la que se pueden insertar comentarios. Por ejemplo, este es el post original y esto es lo que hace él solo sin que nadie se lo pida.</p>
    <p>Lo dicho, esto me sobrepasa.
    </p>

    Tienes un error de ruta como te dice:

    [quote]Warning: realpath() [function.realpath]: Unable to access /usr/home/adesgana.com/web/blog/wp-admin/wp-content/uploads[/quote]

    Entra en el archivo que te dice en ésta parte:

    [quote]/usr/home/adesgana.com/web/blog/wp-includes/functions.php on line 1767[/quote]

    Como ves aquí te ésta diciendo la ruta en la que ésta el archivo y la línea que debes corregir.

    Archivo functions.php, en éste caso sólo debes entrar en WordPress, en la parte de ASPECTO hay uno que dice EDITOR, ahí te aparece una caja donde aparece el CSS de tu theme, y del lado derecho los archivos que puedes modificar, uno de esos es el FUNCTIONS o Funciones del theme, entra ahí y busca algo que diga:

    realpath("parte donde está la ruta inconrrecta") lo único que debes hacer es borrar:
    wp-admin

    Porque la ruta correcta te debe quedar algo cómo ésto:

    /usr/home/adesgana.com/web/blog/wp-content/uploads

    Espero te sirva, si no entiendes algo, copia todo el texto de functions y pégalo aquí, para poder decirte exactamente donde está el error.

    Saludos y suerte!!

    No me aparece el FUNCTIONS en el editor de wp. Pero si lo abro mediante ftp y miro el código en el dreamweaver, en la línea 1767 me pone:
    [code]if ( realpath($path) == $path )[/code]

    Vamos que no sé cómo hacer, así que seguiré tu consejo y copio y pego todo el functions.php:
